网络环境为课堂教学提供了更加丰富多彩的形式,网络信息以其传统教学媒体所无法比拟的丰富性、直观性和交互性使数学教学进入了一个崭新的天地。网络技术可以突破传统教学在时间、空间上的限制,为学生提供更多创新与发现新知的机会,因而更有利于学生进行研究性学习。本节课教学在《几何画板》的支持下进行,以探究动圆的圆心轨迹为例,由学生进行自主探究,协作学习。借助几何画板的强
The network environment provides more colorful forms for classroom teaching. The richness, intuition and interactivity of network information, which is unmatched by its traditional teaching media, make mathematics teaching a brand new world. Network technology can break the traditional teaching in time and space constraints, to provide students with more opportunities for innovation and discovery of new knowledge, which is more conducive to students for research learning. The teaching of this lesson is carried out under the support of Geometrical Sketchpad. Taking the exploration of the center of the moving circle as an example, the students conduct self-exploration and collaborative study. With geometric Sketchpad strong
